BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to pest control dusting, and more particularly to a device for dusting in remote areas using compressed air. Thus, the present invention device is a remote duster that advantageously permits a user to deliver pest control powder (referred to as “dust” in the pest control industry) at an elevated location via a nozzle at a remote end of an extension pole with a portable compressor to cyclone and blow the dust at the desired location to exterminate pests such as bees, hornets or other pests. The compressor may be attached to the pole via an air line, and may be hand held or shoulder-mounted, and may be battery operated. In the present invention device, while the compressor is conveniently located at or near the lower end of the pole, the dust is stored in a container or preferably clear, graduated storage reservoir located at the far (distal) end of the pole. This eliminates air line clogging and permits controlled and measured application of the treatment, significant advantages over the prior art devices.

2. Information Disclosure Statement

The following prior art id representative of the state of the art in the field of pest control dusting devices:

U.S. Pat. No. 6,003,787 describes an insecticide spray apparatus for spraying insecticide in confined areas. The apparatus has a spray gun and a compressor assembly for providing compressed air through a flow line to the spray gun. A nozzle atomizes the insecticide for fogging operations and a trigger on the apray gun provides on and off control of the spray action. The compressor assembly has a base with a handle such that the compressor assembly can be carried in one hand by the user. A plurality of bottle holders are provided on the base for carrying spare pesticide containers.

U.S. Pat. No. 5,768,907 describes a sanitary pest control system that includes a housing with an air conditioning dsiposed within a hollow interior of the housing. The air conditioning system has a power cord extending outwardly form the housing for coupling with an electric outlet. A power switch is disposed within a top wall of the housing. The power switch is electrically coupled with the air conditioning system for selective activation or deactivation thereof. A temperature control panel is disposed within a forward wall of the housing and operatively coupled with the power switch and the air conditioning system to adjust air temperature. An air release nozzle couples with respect to the housing and is in communication with the air conditioning system.

U.S. Pat. No. 4,953,792 describes a dry pesticide applicator that includes a fluidizing medium secured within a housing. A blower mechanism generates a flow of air through the fluidizing medium to establish a fluidized bed within the housing. This fluidized bed is drawn into a dusting by means of a venturi to create a powdered stream. Whenever the dispensing mechanism is inoperative, the fluid flow which creates the powdered stream (by drawing the fluidized bed through a powder inlet) is directed into the housing through the powder inlet to purge any accumulation of powdered material therein.

U.S. Pat. No. 4,5553,698 describes a pneumatic pesticide duster for use in the application of pesticide dusts in structures. The apparatus comprises a dust reservoir, compressed air source, manually operated control valve and metallic discharge tube having an opening ranging in size up to about ¾ inch capable of imparting an electrostatic charge to the expelled air/dust mixture such that dust is attracted to the walls of the structure and the areas to which the pesticide is confined can be closely controlled.

U.S. Pat. No. Re 30,993 describes a compression-type spray device employing a single nozzle that can be used to spray materials varying widely in density, composition and particle size. The device incorporates an air-and-material mix control using variably exposed slots in the nozzle to regulate the flow of high pressure air through the nozzle. A material supply control having variable restrictions may be provided in the material supply tube inlet to regulate the flow of material to the nozzle.

Notwithstanding the prior art, the present invention is neither taught nor rendered obvious thereby.

SUMMARY OF THE INVENTION

The present invention relates to an automated pest control dust applicator device for remote applications, such as bug or bee or hornet spraying in high areas, e.g., trees, overhangs, porch roofs, dormers, eaves, etc. Historically, ladders are used to reach high places with had held sprayers. Alternatively, high pressure sprayers are used from the ground, and these may be aerosol type sprayers, but are sometimes compressor-based sprayers. However, the compressor-based sprayers are bulky and usually require outlets, or are run by generators from vehicles. Most significantly, all of these compressor-based systems have had dust reservoirs at or near the compressor and/or user for easy filling, but these arrangements result in clogged lines and frequent cleaning requirements.

By its unique components and arrangements of components, the present invention provides a superior device that requires less maintenance and greater efficiencies than heretofore achieved. Thus, the present invention automated pest control dust applicator device includes: an elongated support pole having a predetermined length and having a distal end and a proximal end; a dust dispensing nozzle located proximate the distal end of the pole, and connected to a dust reservoir; a conduit and a compressor, with appropriate controls.

The dust reservoir is located at the distal end of the elongated support pole. By this is meant that it is mounted of otherwise connected to the end or near the end of the pole that would be the more distant from user, i.e., at or near the top of the pole. The dust reservoir has an air inlet connected to the conduit, and has an outlet connected to the dust dispensing nozzle for dispersion of the dust.

The conduit may be tightly affixed to the pole, loosely affixed to it or merely hung from the reservoir. The conduit has an upper end and a lower end, and it is connected to the dust reservoir at the conduit upper end. The conduit extends from the dust reservoir a substantial distance in length along the elongated support pole and is connected at its lower end to an air compressor.

The air compressor is connected to the conduit at its lower end, such that, when the reservoir is loaded (e.g., half filled) with pest control dust, and the air compressor is activated, air travels up the conduit, into the reservoir, picks up pest control dust, and air with the pest control dust exits the dust dispensing nozzle for targeted, accurate dispensing of the dust. The automated pest control dust applicator device compressor is a portable compressor, and typically includes a rechargeable power source.

In some preferred embodiments of the present invention, the automated pest control dust applicator device for remote applications has a nozzle that is connected to a ported cap, and the ported cap is removeably connected to the dust reservoir to permit easy access and easy filling. The conduit may be a flexible hose of tube and may be connected to the air compressor via a quick release connector. Likewise, the conduit upper end may be connected to the dust reservoir via a quick release connector, and this is preferably located at a lower portion of the dust reservoir.

The automated pest control dust applicator device for remote applications may employ any workable reservoir, as long as it is upstream from the compressor and the conduit connecting the compressor to the reservoir. It is a critical feature of the present invention that the reservoir be located at or near the far or top end of the pole. The dust reservoir is preferably a transparent dust reservoir, and may be graduated, i.e. have markings on it to indicate powder level. It could be made of clear plastic, such as polyvinyl (polyvinyl chloride). The dust reservoir may be a threaded container at its top to permit easy access and refilling, as mentioned, and could be fabricated out of threaded piping, such as clear plastic tubing, with threads at the top and bottom, and with appropriate closures at each end, e.g., a threaded polyvinyl dust reservoir.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

FIG. 1 illustrates a block diagram of the present invention pest control dust applicator device in accordance with the foregoing and following teachings. As shown, pole 1 has a reservoir 3 located at pole top 5. Reservoir 3 has an outlet to nozzle 11. Compressor 15, with compressor air controller 13, is connected via conduit 7 to reservoir 3. As described above, a user will add pest control dust, for example, drione dust or other available and well known powder, to reservoir 3. Subsequently, when the user is at a difficult (remote or high) area to make a dust application to eliminate pests, the user will turn on compressor 15 at an on/off witch (not shown), place the nozzle 11 in a desired area to be treated, and activate the compressor air controller 13 to give a short spray of dust. The pole may be of any predetermined length, and may be of light weight material. For example, the pole could be made of light plastic or aluminum, and be five to twelve feet in length. Alternatively, the pole 1 could be an extension pole, like a swimming pool vacuum or skimming net pole, that could extend from ten to sixteen feet.

Conduit 127 is connected to brass fitting 123 via quick release connector 125, for inputting forced air into the reservoir. Top fitting 109 is an open fitting with an outlet. It is permanently (e.g. with glue) or removably screwed onto tube 101 and has a threaded male top component 115 for receiving threaded cap 117, with outlet 119 to nozzle 121, as shown.

FIG. 4 illustrates another preferred embodiment of a present invention device 200 with an telescoping extension support pole. Here, the pole has a lower section 201 and an upper section 203 that are interconnected so that upper section 203 is slideably connected to telescope in and out of lower section 201. at pole distal end 205 is a pest control dust reservoir 211 with exit nozzle 213, as shown. Reservoir 211 has fill means (not shown) and an air inlet 215 that is connected to conduit 219 via quick release connector 217. Conduit 219 is connected at its lower end to battery operated, portable compressor 221. Compressor 221 has a compressor on/off switch 223, and an air release button 225, for instant, controlled firing of the device. The extension feature of the pole allows for height adjustment, and the device is otherwise used as device 50 described above.

Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
